3 Claims. (Cl- 215-9) This invention relates to caps for bottles andmore particularly to screw caps.

An object of the present invention is to provide a safety screw capparticularly designed for use on bottles containing a poison or the likeand which is of such a construction, combination and arrangement ofparts as only one thoroughly familiar with the structure of the cap can,other than by chance, properly remove the cap from the bottle.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawing wherein:

Figure 1 is a view showing in section the improved cap with the parts soarranged as to permit the relative movement thereof.

Figure 2 is a view similar to Figure 1 with the parts so relativelyarranged and engaged as to transmit movement of one part of the cap tothe other to effect a removal or replacement of the cap.

Figure 3 is a detail view taken substantially on the line 33 of Figurel, and

Figure 4 is a sectional view through the outer or false cap member.

Referring to the drawing by reference numerals it will be seen that thecap, in the preferred embodiment thereof, comprises in accordance withthe present invention a main cap I consisting of a suitably shaped body,preferably a cylindrical body having a threaded socket portion 8 for thethreaded reception of the neck 9 of a conventional bottle I0. If desiredthere may be suitably arranged in the inner end of thesocket of the capI a cork or other sealing element II.

The cap member 1 is housed within what may be termed a false cap memberI 2.

The cap'member I' 2 which may be formed of metal or other suitablematerial is materially larger than the cap member 1 and is in the formof a closed casing except for an opening I3 in the bottom thereof:registering with the socket 8 and accommodating the neck 9 of the bottleIII.

The cap member;'I- 2- is normally loosely mounted with respect tofthecap member I so that the member I2 may be'rotated or otherwisemanipulated without normally affecting the cap member I.

Further in accordance with the present invention the cap member I in thecrown thereof is provided at any two desirable points thereon withsockets or recesses I4 while the cap member I2 on the under side of thecrown part thereof is providedwith protuberances or pins I5 cooperablewith the sockets It for placing the cap member I2 in such engagementwith the cap member I that a rotative movement of the member I2 will beimparted to the cap member I either for screwing the cap onto the neckor for unscrewing the cap from the neck of the bottle.

Interposed between the crowns of the cap members I and I2 is a springdevice in the form of a disk I6 of spring metal or the like secured tothe crown of the cap I at the center of said crown and in any suitablemanner, Radiating from the disk 6 are upwardly directed curved fingersI! that normally engage the crown of cap I2 to yieldably hold the crownof the cap I2 raised with respect to the crown of the cap 1 andconsequently the projection I5 out of engagement with the recesses I4.

From the above it will be apparent that normally the cap members are inthe relative position shown in Figure 1.

When for example it is desired to remove the cap from the neck 9 adownward pressure is exerted on the cap member I2 against the oppositionof spring fingers I1 and the member I2 is also properly rotated relativeto the member 1 to position the protuberances or projections I5 intoengagement with the recesses I4 for locking the cap members I2 and Itogether. When thus locked together rotative movement of the cap memberI2 in the proper direction will be imparted to the member I forunscrewing the member I to remove the cap from the bottle.

To replace the cap pressure is exerted on the cap member I2 to engagethe projections I5 with the recesses I4 and while so engaged therotation of the member I2 in the proper direction will result in atransmission of movement to the member I for threading the same onto thebottle neck 9.

It will be seen that a cap of this character will require certainknowledge on the part of the user as to the construction of the capbefore a removal of the cap can be eifected other than perhaps bychance. Thus a cap of this character will be especially useful for useby druggists and the general public for containers containing poison orother kinds of medicine or the like that is not to be opened by childrenor persons under irrational impulses.

Having thus described the invention, what is claimed as new is:

1. In a cap of the character described, inner and outer complemental capmembers, said inner cap member fitting loosely within the outer capmember, a disk interposed between the crowns of said cap members andsecured to the crown of the inner cap member, and upwardly directedcurved fingers integral with the edge of said disk and engaging thecrown of the outer cap member for yieldably retaining the crowns or saidcapmembars in spaced relation, and inter-engaging means on the'crownsoi. said cap members adapted to be'engaged in opposition to said fingersfor transmitting movement of the outer cap member to the inner capmember.

2; A cap for bottles or the like comprising an inner cap adapted to beapplied to a bottle or the like by turning it, an outer cap covering theinner cap. means retaining the caps assembled but permitting relativerotary movement thereof, a spring device interposed between the crowns0! said cap members yieldably spacing said crowns apart, said inner capmember having recesses in the crown thereof, and said outer cap memberand normally free to rotate relative to the main cap member, a springdevice interposed between the crown ends of said cap members fornormally spacing said crown ends relative to one another, andinter-engaging means on said crown ends of said cap members adapted tobe engaged in opposition to said spring means for transmitting movementof the false cap member to the main cap member.
